Unable to create template with Analyzer

Elastic Stack Elasticsearch
1

Hello,

I was able to create an analyzer and use it on a single Index. Now, I would like to apply this to an Index template, so that whenever a new index (with Date attached to it) is created, this analyzer can be applied.

When trying to create the template it is giving me an error. Clearly something I am doing is not correct, but just could not figure out what..

PUT _template/textstrings

{
  "index_patterns": ["*event.abc.v1*"],
"settings": {
  "index": {
    "analysis": {
      "filter": {
        "ngram_filter": {
          "type": "nGram",
          "min_gram": "3",
          "max_gram": "20"
        }
      },
      "analyzer": {
        "title_analyzer": {
	          "type" : "custom",
	          "tokenizer": "standard",
          "filter": ["ngram_filter"]
        }
      }
    }
  }
},
"mappings": {
  "doc": {
    "properties": {
      "content": {
        "properties": {
          "title": {
            "type": "text",
            "analyzer": "title_analyzer"
          }
        }
      }
    }
  }
}
}

The error I receive is the following:

{
  "error": {
    "root_cause": [
      {
        "type": "not_x_content_exception",
        "reason": "Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"
      }
    ],
    "type": "not_x_content_exception",
    "reason": "Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"
  },
  "status": 500
}

Thanks to take a look.

Best regards

Hello ... any possible help here ?

You have a blank line been the PUT _template and the json. Which makes it fail I think.

This works well on my end:

PUT _template/textstrings
{
  "index_patterns": ["*event.abc.v1*"],
"settings": {
  "index": {
    "analysis": {
      "filter": {
        "ngram_filter": {
          "type": "nGram",
          "min_gram": "3",
          "max_gram": "20"
        }
      },
      "analyzer": {
        "title_analyzer": {
	          "type" : "custom",
	          "tokenizer": "standard",
          "filter": ["ngram_filter"]
        }
      }
    }
  }
},
"mappings": {
  "doc": {
    "properties": {
      "content": {
        "properties": {
          "title": {
            "type": "text",
            "analyzer": "title_analyzer"
          }
        }
      }
    }
  }
}
}

Thanks a lot. Looks like it was an issue. Once I have removed the space, it fails with a different error:

    {
  "error": {
    "root_cause": [
      {
        "type": "action_request_validation_exception",
        "reason": "Validation Failed: 1: template is missing;"
      }
    ],
    "type": "action_request_validation_exception",
    "reason": "Validation Failed: 1: template is missing;"
  },
  "status": 400
}

Strange that it has worked on your end. I have checked the text and is the same. So, not sure what is missing

Probably you are using a 5.x version

6

Yes. I am using version 5.6 version.

So read the docs for your version: https://www.elastic.co/guide/en/elasticsearch/reference/5.6/indices-templates.html

Thanks a lot David. My bad on that. I have tried so many combinations before posting the issue here, that I forgot that I might have used the syntax of other versions.

It works now.

Thanks for your help.
